  • Detail

Sichuan Jingkong Valve Manufacturing Co., Ltd. successfully developed and applied the pressure balanced plug valve for the operation and maintenance of oil and gas long-distance pipelines, which is mainly used for the blowdown and pressure relief of oil and gas long-distance pipelines to ensure the effective operation of long-distance pipelines. Before 2012, more than 95% of China's pressure balanced plug valves were imported to meet the needs of China's oil and gas pipeline projects. 2012

the pressure balanced plug valve used in the operation and maintenance of oil and gas long-distance pipelines is mainly used for blowdown and pressure relief of oil and gas long-distance pipelines to ensure the effective operation of long-distance pipelines. Before 2012, 95% of China's pressure balanced plug valve products declared by the national non ferrous metal Standards Commission to formulate the national standard for ceramic aluminum new materials were imported to meet the needs of China's oil and gas pipeline projects

in 2012, inspired by the spirit of the national medium and long term scientific and technological development outline (2006 ~ 2020) and the several opinions of the State Council on accelerating the revitalization of the equipment manufacturing industry, Sichuan Jingkong Valve Manufacturing Co., Ltd. took the lead in responding to the national strategic call to promote the localization of major technological equipment, Actively organized technical forces and started the project approval of "operation and maintenance equipment for long-distance oil and gas pipelines - innovative research and development project of pressure balanced plug valve". In the same year, the company signed the "2012 Sichuan major technical equipment innovation and development project plan agreement" with Deyang economic and Information Technology Commission of Sichuan Province, implemented the innovation and development task of pressure balanced plug valve, an operation and maintenance equipment for long-distance oil and gas pipelines, and obtained special funds for the "Sichuan major technical equipment innovation and development" project

the project was completed as scheduled, and the prototype trial production of nps8 CLASS600 and nps16 class 600 plug valves under pressure balance was completed. Two technical patents were applied, and the project was accepted by the reassembly Department of Sichuan Provincial Commission of economy and information technology, forming a technical system for innovative development of the first generation, that is, the first layer, which is a large collection of pressure balanced plug valves

in 2013, the National Energy Administration encouraged domestic enterprises to implement the localization of major technical equipment. Taking advantage of the special science and technology project "localization of key equipment for oil and gas pipelines" of PetroChina, and in combination with the actual needs of the fourth west east gas pipeline project, the company signed a pressure balanced plug valve localization agreement with PetroChina West pipeline branch in August 2013

the project completed the development task of the domestic prototype of the balanced plug valve specified in the agreement as scheduled, and passed the national scientific and technological achievement appraisal in Beijing in July. The appraisal committee believes that "the main technical indicators of the successfully developed nps6 class 900 and nps16 class 900 pressure balanced plug valves have reached the advanced level of similar foreign products, and can be popularized after industrial tests". After the appraisal of the scientific and technological achievements of the project, the prototype of the project has carried out industrial tests. The implementation of this localization project has formed a technological system for the innovative development of the second generation of pressure balanced plug valves

in the same year, the scientific and technological achievements passed the registration of scientific and technological achievements in Sichuan Province, and NPs class300-900 pressure balanced plug valve was recognized as the first set of products in Sichuan Province for major technical equipment in 2014

from 2014 to 2017, Sichuan Jingkong Valve Manufacturing Co., Ltd. implemented the industrialization promotion activities of scientific and technological achievements based on the innovative research and development achievements of pressure balanced plug valves and localization research and development achievements. The activities were again supported by special funds from the government. In the process of industrialization promotion, it sorted out the first and second generation technology systems, and optimized the developed product technology according to the process field test and user use, A third-generation product technology system with stable quality and reliable safety and technical performance has been formed

the successful development of domestic new products of pressure balanced plug valves has achieved the localization of key maintenance equipment for oil and gas pipelines, breaking the situation of long-term import of plug valves for oil and gas long-distance pipelines in China. At the same time, it has also been widely recognized by industry insiders. The second generation dn400/600lb pressure balanced plug valve developed by the company won the silver medal of the products exhibited in the "2014 7th China International Fluid Machinery Exhibition and 2014 5th China International valve Expo"

the third generation DN500 CLA test project developed by the company: mechanical properties such as static load, tension, contraction, zigzag, shear, peeling, etc. ss600 pressure balanced plug valve won the gold medal of products exhibited at the "2016 China (Shanghai) international valve Expo"

in the past five years, the company is still constantly optimizing and innovating products. From the perspective of specification and model, it indicates that Adidas and covestro, marked by "three bars", have jointly developed a pressure balanced plug valve product system with 1 "--36" series caliber and 150lb300lb400lb600lb1500lb2500lb series pressure class; From the product structure design, the spherical valve body and conical valve body are formed, with and without reinforcing ribs; According to the requirements of the use environment, a series of multi-purpose plug valves, such as buried plug valves, plug valves with extended valve stems, and plug valves with extended sleeves, are designed. According to the valve driving mode, a series of driving systems including manual, electric, pneumatic, hydraulic, pneumatic hydraulic and electro-hydraulic linkage have been completed; The sealing method has developed oil sealing, rail type and forced sealing plug valves. Actively provide customers with options based on actual needs

the innovative development of products has promoted the protection of intellectual property rights. During the implementation of the project, 6 technical patents have been authorized, including 1 invention patent, 4 utility model patents and 1 design patent

1467 sets of

series products have been successfully applied in domestic and international oil and gas, chemical, power and other engineering projects. For example, domestic projects such as Fuling shale gas project, the first line of Sichuan East gas transmission, Fuling, Gaochun, Wuhan Iron and steel, Wuhan ethylene gas transmission station construction project, gasification Handan, Langfang gas transmission station, Sichuan East Gas Transmission Pipeline pressurization, etc; The products have also been successfully applied to international projects such as the initial station of Kjeldahl Wuchang d457 product oil pipeline, Egypt gasco natural gas pipeline, Egypt natural gas power plant pressure regulating skid, including the development of three 36 "600Lb pressure balanced plug valves with the largest specification in the world

product innovation and R & D is the fundamental driving force for the survival of enterprises. The successful application of innovative products not only adds new vitality to enterprises facing the downturn in the oil and gas industry, but also responds to the call for the localization of national major equipment, actively supports the made in China 2025 action plan, and further promotes the stable development of enterprises under adverse market conditions

facts tell us that only through innovation can enterprises have a future, meet the needs of the market, and promote the sustainable development of enterprises
